Abstract
An improved high efficiency suction control valve providing unobstructed fluid flow in its activated suction applied mode for removal of viscous secretions at a low level of applied input suction through the catheter. The valve provides positive sealing between a hand-operated plunger and the valve passageway walls against which the plunger engages by slightly over sizing the plunger walls such that the plunger walls expand against a further suction passageway. Similar sealing is provided between the plunger and passageway above the suction passageway.
